Color-blended seismic-attribute volumes allow us to highlight structural and stratigraphic edges present within 3D seismic data volumes. Frequency decomposition and the use of additive RGB color blending is one of the methods that we apply to fault mapping.
Another approach in our toolkit is subtractive CMY color blending. This allows us to highlight faults by color-blending 3 independent edge-detection volumes. Dip volumes are often included in this workflow.
The resulting RGB and CMY color-blended volumes allow us to visualize major, and minor, structural features. They are also used as inputs for innovative automated fault interpretation workflows that auto-track discontinuities highlighted within, and across, the color-blended volumes.
